Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78556, here are decompositions:
- 3 + 78553 = 78556
- 17 + 78539 = 78556
- 47 + 78509 = 78556
- 59 + 78497 = 78556
- 89 + 78467 = 78556
- 239 + 78317 = 78556
- 353 + 78203 = 78556
- 383 + 78173 = 78556
Showing the first eight; more decompositions exist.
